(0142-16) This in'vention relates to sporting guns forcinstance'of the double-barrel type, especiallyiof the so calledunderandover barrel type.

According to the presentrinvention the barrels are fixed at their rear or breech end to a hous ing in thestock, wherein a sliding breech block, adapted tocarrylocking and striker mechanisms andv an operating lever therefor, is located.

-An applicationof-the present invention to an under-andover gunis shown in the accompanying-drawings, wherein;-

comprises'a stock onnthe forward or breech end ofwhich is mounted .an approximatelvU-sectioned housing 1, a sliding breech- 3, housedtherein and-thebarrels which are carriedina block housing. The sliding breech block-.3 is, approximately L-shaped, they-shorter limb being disposedvertically within the housing 1, whilst the longer limb, extends rrearwardly away from the barrels and isadaptedywhen the breech is open,

toextend rearwardly behind the said housing.

-'Anoperating: lever 4 is pivoted to the upper part of thebreechrblockz at its end 5 remote from -the saidsbarrels and on the free: end 13 of said 5 lever iar'e i'suspended two =arms or :ikeys 110.

The gun shown the-accompanying-drawings The connection between-thelever Land the keys 10 -is effected 'by a pin 12 passing, through the former and engagingzinvinclinedslots in-the up per ends of thelatter; ieach'of the keys is provided with two'lugs-9 11, located one above the other withia space betweenflthem, whilst the'block' 3 is provided on either side with a horizontal rib 45; the purposes of said lugs' 9, 11 and ribs ,45'will be described later. a v

Theleverll isprovided on its underside and intermediate its extremities with a-hook or nose 30, which is adapted torengage on the underside ofva'nose 29 formed on the upper half of formstance one cockingleverfl27 pivoted at 28intermediateits extremities, to the horizontalliinb of the breech-block 3 thelower part 31 of said-lever extendsrdownwardly and is located within a slot or recess 32 in'the' twocparallel strikers orpercussion' pins 33 dispo s'ed the. samehorizontal plane andslidablyhoused within' the said'limb of the breech block 3 and-controlled coil springs 35.

The said strikers-33 extend rearwardly to-"the end a of the breech block remote from the barrels and each is provided-on its rearward extremity with a hookor recess-34, each of. said hooks] or recesses 1 being adapted to be-engaged, when the block is-pushed backwards-in the housing l, by a nose 38 on the upper portion or a tumbler 3'7, pivoted at 36-intermediate .its extremities to the rear end of the horizontallimb oflthe breech block 3;. the lower portions-p39 of the said tumblers 3?? contact when the breechis closed-with levers 40 pivoted at 41;,tothe stock, which levers impinge on-the triggers 42,' 42 in sucha manner that when said triggers are pulled the tumblers 37 are trippedtodisengage their noses 38 from the recesses or hooks 34,topermit of the strikers being impelledforWardly-by .the springs 35, whose fixed ends bear-againstthe wall 43. a

A leafspring-25 is fixed uponlthe top of the breech block, the free end of which spring bears at 26 onthe trip orcocking lever 27 and when thelever- 4 -is.raised,' app1ies a force. to the said lever, through the contacting noses 29, 30, which tends to return said. lever -to its lowered position.

intersected towards'their forward ends by vertical grooves 7-extending from top to the bottom vof each side of the housing 1, whilst internally of the extreme :forward endof said housing are a number of parallel ribs 18 whichare located in "vertical planes and :except where they intersect with the horizontal grooves 6, extend around-the entire internal periphery of the housing. Finally horizontal grooves 15 are formed externally of the upper and breech end of the housing 1 wherei in the ears 17' of a'strap 16, extending across the in vertical planes which are adapted to fit or,

engage between the ribs 18 in the breech end of the housing 1.

To assemble the sliding breech block 3 and" barrel block 2 tothe housing 1, the rearward end of the breech block'is inserted into the open breech end of the housing so that the ribs 45 engage with the grooves-6; the block 15111611 pushed into the housing until thelugs 9, 11, on.

the keys 10 strike against the edges thereof,

whereupon the lever 4 is raised to bring the lugs 11 above the top edge of the housing and the lugs 9 intothe plane of the slot6 whereupon the sliding of the block 3 can be continued until the lugs 9,: 11, are brought into plane of the vertical grooves 7. During this latter rearwardmovement the lugs 9 are forced on to the lower edges 8 of the grooves 6 by the spring 25 acting through the operating lever 2'7, cocking lever '4 and keys 10, hence immediately the lugs are brought into the plane of the grooves 7 they drop vertically downwards and the breech block is lockedinposition by virtue of the lugs 9 and 11 bearing-against the lateral walls of the grooves '7. g

Thestrap 16 is next fitted onto the forward end of, the housing 1 and is pushed backwards a suflicient distanceto permit of the insertion'of the brush end of the barrel block 2 vertically downwards into saidhousingso that the ribs 19 may engage between theribs 1 6: iThe strap 16 is then pushed forward's' so that-it bears any-the solid upper end-2O of the barrel block-2, which latter is thereby locked rigidly in position; 1

s The is loaded by raising the'lever 4whereupon the 'lu gs 9 are again brought'into alignment with the grooves 6, to-permit of the breech block being slid rearwardlywithin itshousing; and the nose 30 strikes a'gainst the' nose 29 andturns the trip or cooking lever2'7 in an anti-clockwise direction, the lower end 31 strikes against'the'rear faces of the-recesses 32 in the strikers 33 and forcesthe latter backwards until the recesses or hooks 34 engage with the tumblers 3'7 and retain same against the action of the springs 35. When the rear edgeot the vertical limb strikesagainst the end wall of the housing -1, cartridges may be inserted into the breeches of the barrels, where--" upon thebre'ech block is slid forward until the v lugs'9and'11 are brought into alignment with the grooves '7 and the block 3 is locked in position. The keys 10 instead of having a sliding connlec tion'with the end 13 of the lever 4, maybe fixed V thereto, in which case the said keys and also the grooves '7 will be curved and the axes thereofwill form arcs of a circle whose centre is located at the pivot pin 5, all as shown in Figure 12.

' Figure 5 of the drawings shows how the forward ends of the pins 33 are provided withtransverse arms 45f 46, which are provided with the percussion pins proper 47, 48, located, for instance, in the prolongation of the longitudinal axes or the barrels. The head portion of the breech block 3 may be provided with slots or cavities 49, 50 within which animated and slide said arms 45, 46.

The tumblers 37 are resiliently held in the position shown in Figures 15 and 16 by springs 51 and stops 52. 1 V

of the breech-block.

The strap 16 may be retained in its operative position for instance by means of a little screw (not shown) passing for instance through the strap and engaging into the barrel-block or into the wall of the breachhousing.

The breech-block 3 may be provided with any kind of cartridge-shell-extracting means, for instancewith elastic hooks oi the kind employed as extractors in automatic pistols.

' Finally, it is obvious that the object of the present invention described above may as well be adapted to single barrel guns and to multiple barvrel guns other than that shown in the drawings. o
